can you write an equation by setting an expression equal to itself. would an equation like this be true

Answers

Answer 1

Answer:
Of course ! An expression is always equal to itself.

But if there's, say, an 'x' in the expression, then such an equation would be true
for x=every possible number. You might say it has an infinite number of solutions ...
which certainly has to be true, because no matter what you do to an expression,
it's still always equal to itself !

Answer 2

Answer: yes it would be as long as it truly equals eachother

How do you combine like terms of #-10+7x+24-2x#?

Answers

You should first add -10 and 24. Then you should subtract 7x and 2x. All you have to do is to find the like terms ( 7x and 2x because they both have x’s, and -10 and 24 because they don’t have x’s). So your answer would be 14+5x. If you have any questions please reply.

the area of a rectangle is 52 in². the length of the rectangle is 9 in. longer than the width. what is the width of the rectangle? 8 in. 6 in. 4 in. 3 in.

Answers

length, l = width, w + 9
l = w + 9

area = length * width
52 = l * w
52 = (w+9) w
52 = w^2 + 9w
w^2 + 9w - 52 = 0
w^2 + 13w - 4w - 52 = 0
w (w + 13) - 4 (w + 13) = 0
(w + 13) (w - 4) = 0

length = 13 in
width = 4 in

The proof of the question is explained in the solution.

What are vertical angles?

Vertical angles are the angles that are formed when two lines intersect each other at a point.

Given that a figure having m∠QVR = 49°, we need to prove that x = 15,

We know that,

Vertically opposite angles are equal.

From the figure we can see a number of line segments

m∠QVR = 49°

From the given figure we get,

∠QVR and ∠UVT are vertically opposite angles.

Therefore,

m∠QVR = m∠UVT

49 = 3x + 4

3x = 49 - 4

3x = 45

x = 45/3 = 15

Hence, proved.
